15.2 RAID 1 Logical Drives

A RAID 1 logical drive is built from two physical drives, where one physical drive is a mirror of the other (the same data is stored on each physical drive). Compared to independent physical drives, RAID 1 logical drives provide improved performance, with up to twice the read rate and an equal write rate of single physical drives. However, capacity is only 50 percent of independent physical drives.

If the RAID 1 logical drive is built from different- sized physical drives, the free space, drive segment size is the size of the smaller physical drive, as shown in this figure.
